WEIGHING-SCALE Specification oi Letters Patent.

Application filed .Tune 2'2, with. Serial No. 589,1937

To all whom it may concern:

Be it known that I, FnXN-K P. DUNN, a citizen of the United. States, residing at Anderson, in the COK IBLty of Madison and State of Indiana, have inventeda new and useful lVeighing-Scale, f which the follow ing is a specification.

An object of my invention is to produce a weighing scale'havinga loadoeceiving platform which is raised but very little above the surface upon Which-the scaie structure is supported, thus reducing very materially the amount of labor required in raising successive quantities of com olities to weighing (position.

A further object of my invention is to" provide a weighmg scale having a scale-'- bea in u'pon which is mounted. on automatically 'shiftahle counterpoise arm which itself serves to counterbalance the weight oi. the c0mmodityreceiving platform and. to connect the scale-beam with an indicating drum upon which may be arranged a multiplicity of sets of graduations indicating aggregate valuesof differently priced coin modities. I v w The accompanying drewings illustrate my invention.

Figure 1 is a vertical section of a scale constructed in accordance with my invention and Fig. 2 a fragmentary elevation of the commodity-receiv1ng platform and supporting base.

In the drawings, 10 indicates it suitable supporting base which should preferably be made very low; especially at that end adjacent the commodity-receiving latform. Extending upwardly from the base 10, upon opposite sides thereof, are two separated brackets 11, 11 each of which, at its upper.

end, is providedwith a crotch hearing 12 adapted to receive the knife edge iuicrum 13 of the baiancing beam 14. The beam '14 is bifurcated or yoked at its commodity-re eiving end so that each knifeedge .13 is carried by one of the arms of the yoke, and beyond the knife edge 13 eachmrm of the yoke is provided with an upwardly-presented knife edge 15 adapted to receive a crotch block ,16 carried at the upper end-0f racemes Jan. 23, 1911.

an arm 17. Thetwo arms 17 are carried at opposite ends of a commodity-receivin platform 18 and secured to these arms 1 and form 18, from engaging the scale-beam."

The arms 17 depend considerably below the crotch block 16 so that the commodity-recciving platform may lie very close indeed to upper surface of the base 10. The sonic-beam H must, of necessity, be at a considerable height above the surface 20 upon whichthe base 10 may rest but, by the arrangement shown, the commodity-receiving platform 18 may he placed within a coupic of inches of this surface thus materially iesscning' the labor of placing commodities upon the receiving platform. o

iVhile my improved commodity-receiving platform'may be used in connection with the beams of different types of scale, it is especially adapted for use in connection with the particular type of scale-beam which I have shown in the present-drawings. The long arm of the scalcfheam 14 is bifurcated at 21 so as to form a pair of arms between which is mounted, on suitable knife edges 22, a depending counterpoise arm.23 the lower end of which carries a weight 24 which, in its :normel depending position,

balances the weight of the platform 18 and associated parts. The counter-p ise arm and weight together constitute I a counterpoise the scale, as is evident from an inspection ofe drawing. The base T is provided with ah opening or cutaway portion '10 within which the lower cndof the pendulum depends and a stop or buffer 24' is secured to the base with. its end projecting into the opening to form a stop or limit for the t movement of the pendulum. Secured to arm vlded at opposlte brackets, limbs of the beam 1n close mg the platform 18 23bcyond knife edge 22 is a cam 25 which partakes of the swinging movement of the weighted arm 23. Secured to the upper end of cam 25 is one end of a flexible, but nonstretching, tape 26 the lower end of which is adjustably connected to the base 10 by means of an adjusting screw 27.

Pivoted at 28 upon beam 14 is the .lower end of a rack bar 29 the upper topthed end of which meshes with a pinion 31 carried by the indicator drum 32 which is su tably journaled on av horizontal axis in the upper part of an inclosing casing 33 carried or formed integral with base 10. That portion ofqcasing 33 which incloses drum 32 is prosides with sight openings 34 and 35 through which the indicating divisions of the drum are visible to the customer and the operator respectively.

Any. suitable means may be used for keephorizontal, either a hlgh check or a low check being available for this purpose. ings I have shown a low check ing of a link 41 pivoted at 42 to the base 10 and at 43 to a bracket 44 depending from platform 18. 'A suitable dash pot 51 is rovided to steady the movement of the beam.
